Axiom type
LLM classification basis: function-based → ≡
The identity-giving trait across all three definitions is designed-for-transport storage capacity ("a tank which is supposed to be transported"; "transportable... container, safe for the transportation and storage of a wide range of liquids"), not a described physical mechanism or geometry. No source names a structural configuration (frame, skid type, connection standard) that would ground a constructive differentia.

COPI-Core operation
⚠ Process parent
PlannedProcess reaches no COPI-Core operation, and no gap (out of scope / coverage gap) is recorded.
LLM rationale:
Every source defines tote tank as a tank whose reason for being is transportability of its stored contents ("supposed to be transported"; "transportable... container"). This is more specific than plain StorageFunction (already enriched via storage tank/basin/hopper/silo/accumulator/pressure vessel) — every realisation of PortableStorageFunction is a realisation of StorageFunction (liquid is held), but not every StorageFunction realisation is portable (a fixed storage tank is not). This is the Subtype case, not Reuse: co-extension would require every storage-function-bearer to also be transportable, which is false for the sibling classes already in the ontology.

Genus (genus proximum)
Most specific superclass — may be a domain class like "Valve" or an IOF-Core root.
BFO/IOF-Core Root
bfo:Object branch
bfo:ObjectAggregate branch
bfo:ImmaterialEntity branch
LLM rationale:
Source hierarchies offer ARTEFACT, TANK, and Static Equipment as parent candidates, none of which is itself an enriched class in this ontology. The established, already-enriched genus for containment/storage equipment of this kind is Vessel (used consistently by storage tank, basin, hopper, silo, accumulator, pressure vessel, pig launcher, pig receiver) — its own function is ContainmentFunction, genus_bfo_root Assembly, and it is the most specific genuine superclass available given no separate 'Tank' class exists yet in the ontology. Following the sibling pattern (storage tank -> Vessel) rather than introducing a new unenriched 'Tank' genus keeps tote tank correctly inheriting Vessel's containment axioms.

Conditions that distinguish
Tote Tank
from sibling classes under genus
Vessel.
Only what is not already entailed by the genus.
Differentia expression
Differentia (natural language)
LLM rationale:
PortableStorageFunction is the minimal additional condition: it is not entailed by Vessel's own ContainmentFunction, and it is exactly what every one of the three source definitions independently emphasizes as the concept's reason for being.

Necessary Parts

Frame
▼
Consider part-whole relations beyond subsumption:
hasComponentPartAtAllTimes (universal, structurally essential)
· hasComponentPartAtSomeTime (contingent, optional component)
LLM rationale:
Frame identified via Step 2b secondary-source research (DNV-ST-E271), absent from the three terms.db definitions alone.

Process Participation Signature ⟨I, O, T⟩
✓ done
PortionOfLiquid → PortionOfLiquid
▼
Inputs (I)
Outputs (O)
Transformation (T)
LLM rationale:
The signature mirrors Vessel's own containment signature (liquid in, same liquid out) — the differentiating characteristic (transportability) is a property of the process context (repeated relocation) rather than a distinct participant type, so it is captured in the transformation phrase, not as a new input/output type.
